Folic acid, a form of vitamin B9, is primarily used for:
- Preventing and treating folate deficiency anemia by helping the body produce healthy red blood cells
- Supporting proper brain, skull, and spinal cord development in fetuses during early pregnancy, thereby preventing serious birth defects known as neural tube defects such as spina bifida and anencephaly
- Lowering high blood levels of homocysteine, which is linked to cardiovascular disease and stroke risk
- Reducing side effects caused by the drug methotrexate, such as nausea and vomiting
- Potentially improving memory and cognitive function in older adults, supporting mood in depression, and lowering blood pressure in some cases
- Promoting overall cell growth and repair, benefiting rapidly dividing cells like those in hair, skin, and nails
- Supporting healthy pregnancy and fetal development, with recommendations for women of reproductive age to take 400 mcg daily to reduce risk of birth defects
In summary, folic acid is vital for cell growth, red blood cell formation, fetal neural development, and reducing certain health risks related to cardiovascular and neurological conditions
